"Ok O'reilly is rude to his guest but he is not afraid to invite who disagree with his views."

I don't agree with some other things you wrote, but "O'Reilly not being afraid of guests" and "inviting" them goes much more than the realm of words that you mean them to imply. Who owns the show? Bill O'Reilly (or/and his bosses). Who is loud and vicious? Bill O'Reilly. Who talks more on O'Reilly's interview session? O'Reilly himself!

If you can bash someone in your own show and call yourself a "professional interviewer," there is no more stupidity than that.

Just take a look at the video I posted where he interviews a democratic mayor, Rocky Anderson. More than half of the interview session he spends calling the interviewee names (foolish, cooky, stupid, liar). I haven't seen anybody that is this vicious and blatantly attacks his guests.
